    nice sink

    from Decatur, IL – Verified Buyer– Top 1000 Reviewer

    I have not yet installed this but did just install one in my laundry room that is a single basin. I purchased the cafe brown and it is beautiful. Really modernized my laundry room. Cannot wait to see this one put in my kitchen. Purchased the matching faucet in the same color.
